How micro-segmentation creates an uphill battle for intruders

2021-04-22 05:30

An effective phishing attack may allow an attacker to establish a beachhead without any credential theft.

Network micro-segmentation plays a central role in the realization of zero trust strategies by severely limiting the lateral movement of an attacker and obstructing their ability to navigate the network.

Dividing up environments effectively shrinks the attack surface available to adversaries and provides extremely granular control of all cloud and data centre environments, down to being able to segregate individual workloads.

The tier segmentation was so restrictive that we observed blocked connection attempts drop significantly as the attacker was forced to try other methods.

The results of our exercise couldn't be clearer: even the most basic level of micro-segmentation turns lateral movement into an uphill struggle for attackers, while the most restrictive policies mean they might as well be trying to summit Everest.

As the segmentation becomes more extensive and complex, attackers will take more time to navigate the network.
